APPARATUS FOR MANUFACTURING AXLES.

SPECIFICATION forming part of Letters Patent No. 599,638, dated February22, 1898.

Application filed December 16, 1896. Serial No. 615,908. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES M. SOHWAB, of Munhall, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Manufacturing Axles, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawing, forming part of this specification, in which thefigure is a diagrammatic plan view showing my improved apparatus for themanufacture of axles and similar articles.

My invention relates to the forming of axles by hammering them intoshape from billets or pieces of steel. Heretofore in presenting thepiece of steel to the hammer the ordinary rectangular or square billethas been employed, and the capacity of the hammer is very much reducedby the use of such square or rectangular billet,

My invention is designed to greatly increase the capacity of the hammerand reduce the cost of the axle, as well asto improve the quality of thesteel; and to that end it consists, broadly, in placing between theheating-furnace and the hammers a pair of rolls by which the squarebillet may be reduced to a round or cylindrical form before it passes tothe hammers.

In the drawing, in which similar numerals indicate corresponding parts,2 represents the heating-furnace, in which the square billet is broughtto a proper temperature and from which it is taken by any suitabledevice, such as a truck moving on a track 3, to the roller-table 4 of aset of reducing-rolls 5, through which the metal passes and in which itis reduced at a single pass from a square to a round billet. The roundbillet emerges on a roller-table 6, from which it is taken by a suitableappliance-su ch as a truck moving on a track 7, an overhead crane, orsimilar deviceto one of several hammers 8, by which the round billet isfinished into an axle.

The advantages of my invention will be apparent to those skilled in theart, since the square billet is reduced to a cylindrical form in therolls, which do part of the work ordinarily accomplished by the hammers,and the forging is then finished under the hammer at the same heat. Thecapacity of *the hammers is thereby greatly increased, while the cost ofthe axle is reduced and its quality improved.

It is evident that the rolling-mill or rolling device may be of anydesired construction and operated by either steam, .electricity, orhydraulic pressure, and the billet may be reduced by either one or morepasses, so as to produce a round billet from a square one, and manyother changes may be made in the form and arrangements of the partswithout departing from my invention, since I consider myself the firstto combine with a hammer for forming axles or similar articles arollingmill by which the square billet is reduced to a round beforepassing to the hammers, the operation being accomplished without thenecessity of reheating.

I claim- In the manufacture of axles or similar articles, thecombination with rolls arranged to reduce a heated square billet tosubstantially my hand.
